Triangle wxy, with a vertex ∠x at (3, 0), is rotated clockwise 90° about the origin. which of the following rotations is equivalent to 90° clockwise rotation about the origin?

a. clockwise 270°
b. counterclockwise 270°
c. counterclockwise 90°
d. clockwise 360°

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

the answer is c just got it on ed
